According to statistics released by the World Health Organization, as of 19:49 CET on January 30, (2:49 Beijing time on January 31, the cumulative number of confirmed cases of COVID-19 worldwide reached 10,1561,2919, an increase of 500,985 compared with the previous day; the cumulative number of deaths reached 219. 6944 cases.
The cumulative number of confirmed cases of COVID-19 worldwide exceeds 100 million.
At the beginning of 2020, the COVID-19 epidemic spread in many countries. On February 11, 2020, local time, WHO Director-General Tedros Tedros announced in Geneva, Switzerland that the novel coronavirus pneumonia should be named “COVID-19”.
At a press conference held on March 11, 2020, WHO Director-General Tedros Tedros announced that the COVID-19 epidemic has the characteristics of a global pandemic.
According to the WHO, there were already confirmed cases in 114 countries around the world at that time, after two weeks, the number of confirmed cases outside China increased 12-fold.
Concerned about the alarming extent and severity of the epidemic, WHO determined that the epidemic has a pandemic characteristic. Less than a month later, on April 3, the number of confirmed cases of COVID-19 worldwide exceeded 1 million.
According to statistics released by Johns Hopkins University in the United States, on June 28, 2020, Beijing time, the cumulative number of confirmed cases worldwide exceeded 10 million;
August 11, the number reached 20 million; on November 8, the cumulative number of confirmed cases worldwide exceeded 50 million; as of Beijing time At 3:22 on January 27, 2021, the cumulative number of confirmed cases of COVID-19 worldwide exceeded 100 million, reaching 100032,461, and the cumulative number of deaths was 2,149818.
The number of infected people around the world is accelerating.
At present, the global population is about 7.6 billion, and the cumulative number of confirmed cases exceeds 100 million, which means that one in every 76 people in the world is diagnosed.
Coronavirus may continue to spread for a long time.
Since the middle and late October last year, the number of new confirmed cases worldwide as a whole has shown a sharp upward trend.
According to WHO data, on December 20, 2020, local time, there were 795,942 new confirmed cases in a single day worldwide, the highest since the outbreak of the epidemic.
On January 28, local time, Hans Kruger, head of the European region of WHO, said that the blockade measures taken by European countries have begun to bear fruit, and the number of new confirmed cases in 30 countries has shown a downward trend in the past two weeks.
However, the spread of the epidemic in Europe is still relatively fast, and it is too early to relax the blockade measures.
Kruger also mentioned that in Europe, due to the serious situation of the epidemic, people’s mental health problems have gradually emerged, and “mental health problems have become a crisis parallel to the epidemic.”
Recently, Michael Ryan, head of the WHO Health Emergency Project, said that even if we carry out mass vaccinations for the foreseeable future, the novel coronavirus may continue to spread for a long time unless people can comply with epidemic prevention regulations.
Ryan believes that human beings should not use the elimination of this virus as the criterion for success.
The real success is to reduce the lethality of COVID-19 and prevent it from affecting our economic and social life.
In response to mutant COVID-19, Ryan also pointed out that even if the novel coronavirus evolves to the point where it makes the vaccine ineffective, I believe we can adjust quickly.
United Kingdom: The death rate is the highest in the world
The number of confirmed cases is climbing as the mutant coronavirus is found in Britain.
According to statistics released by Johns Hopkins University in the United States, so far, 157.28 people in the UK have died of COVID-19 per 100,000 people, the highest death rate in the world.
At the same time, the number of hospitalized patients remains high.
According to the BBC, the number of patients needing to use ventilators for treatment has continued to increase since December 18, 2020, from 1,364 at that time to 4,076.
A new study shows that the mutant coronavirus found in the UK may increase the mortality rate by about 30%.
However, Patrick Valance, the chief scientific adviser of the British government, said that the evidence at present is insufficient and some uncertainty remains.
Russia: The number of new confirmed cases in a single day is decreasing.
On March 2, 2020, Russia’s first confirmed case appeared, which took Russia six months from the first confirmed case to 1 million.
From 1 million to 2 million, it took Russia 79 days. 37 days later, the cumulative number of confirmed cases in Russia exceeded 3 million.
According to the epidemic curve released by Johns Hopkins University, the epidemic in Russia peaked in May and December 2020, and the number of new confirmed cases in a single day is currently on a downward trend.
Russian President Putin is optimistic about the epidemic situation in the country.
January 25th local time, Putin said, “At present, the number of new confirmed cases in Russia is decreasing, which is less than 20,000.
The epidemic situation in China is gradually stabilizing, and we may carefully lift the previous epidemic prevention restrictions and return to normal life.
United States: an average of 67,000 people are diagnosed every day
According to real-time statistics released by Johns Hopkins University, as of January 30 local time, the number of confirmed cases of COVID-19 in the United States has exceeded 26 million, accounting for more than a quarter of the total number of cases worldwide, and the cumulative death toll has exceeded 430,000.
On January 21, 2020, the first confirmed case in the United States increased from the first to 25 million cases.
It took just over a year for the United States, which means that the average number of people in the United States is about 67,934 confirmed every day.
According to Fox News, after 2021, the number of new confirmed cases in a single day in the United States began to decline, with the number of new confirmed cases falling from nearly 250,000 to 170,000 per week, and the positive rate of people tested for the virus in the United States also fell from 13% to 9.4%.
However, public health experts still issued warnings.
“We’ve seen a lot of people getting vaccinated against COVID-19, which is a good start, but I don’t think the decline in the number of confirmed cases is tied to vaccination, it’s just that the spread of the epidemic into a ‘natural stagnation’,” said Anthony Fauci, an infectious disease expert.
“As variant’s COVID-19 spreads across the U.S., I have great reason to believe that actual infections are worsening,” Fauci stressed.
Meanwhile, the number of deaths from COVID-19 in the United States remains high.
According to CNN local time on January 25, the average daily death rate in the past week was about 3,088.
India: More than half of the people in the capital New Delhi have been infected
On January 30, 2020, local time, the first confirmed case was discovered in India; sporadic cases occurred in India for the following month. On March 25, the Indian government declared that the whole territory had entered a “lockdown period”.
India’s outbreak gradually broke out after the country entered lockdown, according to a daily graph of confirmed cases released by Johns Hopkins University.
NPR pointed out that India’s economy was unable to support the consequences of the “lockdown”, causing a large number of poor people to be in trouble.
In June 2020, the Indian government began to change its route and gradually lifted the blockade.
Last August, the epidemic in India began to spread to rural areas.
On August 7, the cumulative number of confirmed cases reached 2 million, and on August 23, it exceeded 3 million, taking only 16 days.
Since then, the number of new confirmed cases in India has broken the record one after another, reaching the highest number on September 17 and 97,894 new confirmed cases on that day.
Entering 2021, the epidemic situation in New Delhi, the capital of India, is still not optimistic.
According to India Today, according to the fifth round of serum antibody tests for the novel coronavirus conducted in New Delhi in January, on average, one in two people in the area tested positive, which means that they have unconsciously contracted the novel coronavirus.
Brazil: The number of new confirmed cases in a single day is still at a high level.
On February 26, 2020, Brazil saw the first confirmed case.
However, the country did not immediately take epidemic prevention measures and did not track confirmed cases, resulting in missing the “best window” for epidemic prevention.
According to the daily curve of confirmed cases at Johns Hopkins University, the number of new confirmed cases in Brazil showed a downward trend in a single day in July 2020, but due to President Bolsonaro’s repeated calls for “restarting the economy”, epidemic prevention restrictions gradually relaxed everywhere.
Since mid-November last year, the epidemic in Brazil has rebounded again.
So far, the number of new confirmed cases in Brazil in a single day remains high.
According to the epidemic data released by the Brazilian Ministry of Health on January 30, local time, there have been 58,462 new confirmed cases in Brazil in the past 24 hours.
As the fifth country in the world, Brazil has a total population of about 210 million, and the cumulative number of confirmed cases currently exceeds 9.17 million, which means that in less than a year, 1 in 23 Brazilians has been diagnosed with the novel coronavirus.
More variant’s of COVID-19 may be confirmed in the future.
Since the outbreak of the novel coronavirus, many countries and regions around the world have reported new variant novel coronaviruses. According to incomplete statistics from reporters, there are currently seven new variant coronaviruses in different countries and regions.
According to Nature, COVID-19 belongs to RNA viruses.
When it replicates in the host, these viruses are often prone to genetic variant’s because the enzymes that copy RNA are very easy to make mistakes.
Liam Smith, professor of clinical epidemiology at the London School of Hygiene and Tropical Medicine, said, “RNA viruses are very easy to variant, but most variant’s have no practical significance and do not require us to take additional measures.”
ABC reported that experts pointed out that as the epidemic continues, more variant of COVID-19 may be confirmed in the future. Angela Rasmussen, a virologist at the Center for Infection and Immunology at Columbia University School of Public Health, points out that the best way to protect yourself and others from COVID-19 is still to wear masks, maintain social distancing, avoid mass gatherings and wash hands frequently.
[Introduction to the main variant’s of COVID-19]
D614G variant’s
The D614G variant’s of COVID-19 from late January to early February 2020 gradually replaced the originally discovered strain.
By June 2020, the variant became the main type of COVID-19 transmission worldwide.
The WHO report states that the variant is more infectious and transmitative than the initial strain, but does not cause more serious diseases and does not affect the effectiveness of existing laboratory diagnostics, treatment methods, vaccines and public health measures.
Cluster 5
A new variant COVID-19 associated with mink was found in Denmark from August to September 2020.
According to data from the European Centers for Disease Control and Prevention, the strain does not seem to be more infectious and does not spread widely.
WHO pointed out that the strain contains a combination of variant’s that have not been previously observed, which may shorten the duration of immunity after vaccination.
Relevant research is still in progress.
B.1.1.7
On 14 December 2020, the United Kingdom reported a novel variant novel coronavirus known as B.1.1.7 to the WHO.
In September 2020, the strain was first discovered in Kent, southeastern England.
WHO research data show that the transmission rate of the strain has increased by 40% to 70%.
On January 27th local time, the WHO reported that the variant novel coronavirus reported by the United Kingdom has been found in 70 countries and regions around the world.
On January 22nd local time, Patrick Valance, the chief scientific adviser of the British government, pointed out that the data showed that the mortality rate may increase by 30%, but this is still a “preliminary conclusion”.
British Prime Minister Johnson and his scientific advisers pointed out that existing vaccines are still effective for both the original novel coronavirus and the variant virus.
On December 18, 2020, a new variant novel coronavirus was detected in South Africa.
501Y.V2
According to The Washington Post, genetic scientists in South Africa believe that the strain is 50% more infectious than the original strain.
On January 27th local time, WHO statistics showed that the variant virus had been found in 31 countries and regions.
The strain may escape some of the antibodies already available from a vaccine or natural infection, CBS reported.
“This means people who have been infected are likely to reinfect a new strain, which could make the vaccine less effective,” said Alex Siegel, a senior researcher at the African Institute for Health.
P.1
Brazilian researchers collected 31 positive samples of COVID-19 in Manaus, the capital of the Amazon state, December 15-23, 2020.
A variant novel coronavirus was detected in 13 samples.
The strain was named P.1, carrying E484K, K417T, N501Y and other kinds. variant’s, similar to variant coronaviruses found in the UK and South Africa. These variant’s may make the virus more infectious and may reduce the effectiveness of the vaccine.
On January 27, local time, WHO statistics showed that the variant virus had appeared in eight countries and regions.
Virus experts believe that the vaccine is still effective for P.1 strains.
Variant novel coronavirus found in Germany
On January 18th, local time, according to German media reports, 73 patients and medical staff were diagnosed with the novel coronavirus virus in a hospital in Gamisch-Partenkirchen, Bavaria, Germany, of whom were infected with a new variant virus.
This virus is different from the variant viruses previously found in the United Kingdom, South Africa and Brazil.
It is not clear whether this new variant virus is particularly infectious.
CAL.20C
On January 19th, local time, according to the New York Times, scientists found this new variant novel coronavirus in California, USA.
Researchers say the strain may have appeared as early as July 2020 and did not spread rapidly until November.
In addition to California, researchers have found the strain in more than a dozen states, including Arizona, and in Washington, D.C.
There is no evidence that the strain is more infectious or lethal than other variant viruses, and researchers are studying whether the strain will affect the effectiveness of the vaccine.
